The Atari ST appears, running a color graphical user interface: GEM, from Digital Research, the people who brought us CP/M. But it's not touted as an actual operating system until a decade later. It's marketed as a graphical user interface that extends the DOS operating system and lets users run several programs at the same time and freely switch among them. Microsoft Windows 1.01 retails, at a list price of $99.

BSD will ultimately spawn alternatives to some commercial microcomputer operating systems - and form the core of at least one major commercial operating system, Mac OS X. The godfather of open source is born when the Computer Systems Research Group at UC Berkeley releases a variant on Unix called the Berkeley Software Distribution. It would be the model for command-line DOS variations for two decades. Intergalactic Digital Research's maverick brain Gary Kildall creates CP/M, a simple microcomputer operating system for simple microcomputers.
